Subject: isset and unset behaviour
From: curt@php.net (Curt Zirzow)


Given: 
  $a[2] = '1';
  $k = (double)2;
  echo isset($a[$k]);
  unset($a[$k]);
  echo isset($a[$k]);
  echo " -> expect 1\n";

Results:
  11 -> expect 1

Although a double value isn't a valid array index, it doesn't seem
to be consistent.  I'm thinking that the code should yeild one of
two results:

  1. Issue warning as with using objects or arrays as keys
  2. unset uses the str.val to retrieve the proper index.

Any thoughts on the proper behaviour?

you've been hearing about.  No, sir.  Our model is the trapezoid!
